The spot features a string of undated clips from newscasts reporting Milwaukee was fourth in the nation for poverty and third for unemployment, along with reports on a 2009 property tax hike of 10.1 percent.

After a newscaster says, “It is another hit for a struggling section of Milwaukee,” the spot cuts to an interview with Dr. Marc Levin of the UW-Milwaukee Center for Economic Development, who says, “We’re facing an economic crisis.”

The spot then cuts to black-and-white video of Barrett campaigning as the narrator says, “Tom Barrett has failed in Milwaukee for eight years. Don’t let him take Wisconsin backwards.”

Walker’s campaign had no immediate comment on the spot, which it said would be unveiled later today.
